Pokemon Go Afk Hack

So I was wondering if anyone had any advice regarding this hack idea below.

What the hack does:
-Auto walks around neighborhood in a circle using some sort of gps spoofing
-Engages pokemon's it encounters and captures them

I was gonna just do basic gps spoofing but you can get banned if your gps is just jumping all over the place so its better to change coordinates to a reasonably close location.


So do you guys think this is possible? If so anyone interested in making it and teaching me or pointing me in the right direction to attempt to make it. I feel like it shouldn't be too hard besides the capturing part. As you can get the longitude and latitude of a phone and just have a loop for changing it by adding or subtracting values.
